If biological evolution resulted in the creation of man on Earth, what would have been the purpose of a separate creation of Adam and Eve? Why was it needed? To answer these questions, we have to remember that the creation of Adam was about the correct time in history for God to begin a relationship with mankind, the source of ‘children’ for his future Kingdom of Heaven. Prior to the time of Adam, mankind was too ‘ young’ or ‘immature’ to fully comprehend God and to have a relationship with him. Man was nomadic and looked out for himself and his family to survive. He had no rules or laws to follow and, as far as we know, had no relationship with God. He may have worshipped a god or gods but man did not have God. So at that right time in history, God needed a way to begin a relationship with mankind and move his plan forward. He had reached a time when he needed to start teaching mankind lessons as a father would do today to his young children as they mature. Like for a small child, God had to start out simple showing man the difference between right and wrong using actual people in his demonstrations. I am sure God knew he had a long road ahead of himself in raising mankind.
The story of Adam and Eve contains the first of many lessons to be recorded in the Bible as God started his relationship with mankind. The fall of Adam and Eve has many lessons in itself. When it comes to sin, we learn having all of our needs met, as it was in Eden, is not the solution to preventing sin. Adam and Eve had everything they needed in Eden but fell to greed and the desire for wanting more when tempted by Satan. Thus, sin will enter our lives no matter how much or how little we have. Because of biological evolution, we have that genetic predisposition for always wanting more and succumbing to temptation. It allowed us to survive a long time ago but serves as a source of sin today. We learned about peer pressure in the story of Adam and Eve. Even Eve, one who lived with God, succumbed to peer-pressure from Satan and defied God’s one and only command to not do the very thing she did. The story of Adam and Eve is also a lesson on casting blame rather than repenting for our mistakes. Adam blamed Eve for his eating the forbidden fruit and Eve blamed the serpent for her disobedience even though neither Adam nor Ever was forced to eat from the fruit. They also did not apologize to God for their sin. But that would have been expected since they did know of repentance since they did not know Jesus.
Did God know from the beginning that Adam and Eve were going to fail and thus, the concept of Eden would fail as well? I believe God did. Like many passages in Genesis, the Story of Adam and Eve has an element of prophecy about what is to come in the end as revealed in the Book of Revelations. It is a prophecy having clues to God’s plan for mankind. Christians are taught that Adam and Eve were God’s children in Eden who would have lived forever with God if they had not succumbed to temptation and disobedience. But what if living an eternal life with his obedient children is God’s plan for what will happen in the end after Jesus comes again; not what God expected in the beginning with just Adam and Eve? Evidence to support that it was never God’s plan for Adam and Eve to live in Eden forever is Jesus was not in Eden, only God. There was only one symbolic Tree of Life in Eden - which was God. Christians believe that Jesus was and still is the main player in God’s plan for mankind. As will be discussed, the Book of Revelations states that both God and Jesus will be with man in the end in the New City of Jerusalem. Thus, there will be two Trees of Life in the New City.
The absence of Jesus in Eden indicates it was God’s plan for Adam and Eve to be the start of the lineage leading up to Jesus. Their creation was also the first step in God’s plan for beginning a relationship with mankind; not the whole plan. God’s plan had many more lessons to come. These would be lessons that God would demonstrate using methods much like a scientist would use today to prove a hypothesis to others.
